Bone mineral density in two different socio-economic population groups

Summary We have studied the bone mineral density (BMD) of the lumbar spine in two healthy population groups in Spain with similar characteristics but with different socio-economic levels. BMD was measured in 1116 individuals of both sexes in two selected groups: (A) 832 volunteers in the urban Barcelona area and (B) 284 volunteers from a suburb with lower socio-economic level. Individuals of group A have greater spine BMD than group B. The maximum difference was found in the group between 20 to 39 years: 5% ( P P
